Returning to the United Kingdom, Sesame was later equipped to act as a plane guard within the Home Fleet, with all armament removed and a davit fitted to rescue aircraft.

The vessel remained in that configuration for a short time, but the London Naval Treaty sounded the death knell for the ship as it limited the destroyer tonnage that the Royal Navy could operate.

A full load of 301 long tons (306 t) of fuel oil was carried, which gave a design range of 2,750 nautical miles (5,090 km; 3,160 mi) at 15 knots (28 km/h; 17 mph).

[4] The ship was designed to mount two additional 18-inch (457 mm) torpedo tubes either side of the superstructure but this required the forecastle plating to be cut away, making the vessel very wet, so they were removed.

[7] Laid down on 2 February 1918 by William Denny and Brothers in Dumbarton with the yard number 1103, Sesame was launched on 30 December, soon after the Armistice which ended the First World War.

[12] Five days later, the destroyer arrived in Liepāja along with sister ships Serene, Shamrock, Strenuous and Torbay in time to see peace restored.

On 22 April 1930, the United Kingdom signed the London Naval Treaty, which limited the total destroyer tonnage that the navy could operate.

On 1 November 1930, during a demonstration by the Atlantic Fleet to delegates to the 1930 Imperial Conference, Sesame rescued the three-man crew of a Fairey IIIF aircraft that had crashed while taking off from the carrier Courageous.
